New indices to track global carbon market

us-based Merrill Lynch and France's Socit Gnrale, both global financial companies, launched new carbon dioxide (CO₂) emissions indexes in the last week of March. The indices will track the global carbon market. Merrill Lynch's MLCX Global CO₂ Emissions Index and Socit Gnrale's SGI-orbeo Carbon Credit Index allow investors to access the world's carbon markets, including the European Union's emissions trading scheme and carbon trading markets under the un's Kyoto Protocol. The eu Emissions Trading Scheme's European Union Allowances and Clean Development Mechanism's certified emissions reductions make up more than 99 per cent of global trading activity on greenhouse gas credits.
